hpux long long patch

[law@redhat.com]

It is (unfortunately) necessary to define _INCLUDE_LONGLONG on hpux to make
various long long prototypes available in hpux's header files.  Missing those
prototypes can prevent certain features from being available.  For example,
without those prototypes long long IO support in libstdc++-v3 is not enabled.


This patch has been bootstrapped on my hpux11 machine and is currently
bootstrapping on my hpux10 machine.

	* pa.h (CPP_SPEC): If not in ANSI mode, define _INCLUDE_LONGLONG.
	(CPLUSPLUS_CPP_SPEC): Define _INCLUDE_LONGLONG.
